This study examines the relationship between the learning motivation and conceptual change of 127 eighth graders, after they have learned the acid, base, and salt concept in a digital learning context, designed according to the dual‐situated learning model (DSLM). Two instruments—the students’ motivation towards science learning (SMTSL) questionnaire and the acid‐base‐salt concept diagnostic test (CDT)—were used in the study. The questionnaire and the test were given to students in pre‐test, post‐test, and delayed post‐test. Based on their motivation questionnaire scores, 18 students were selected from various scoring ranges for semi‐structural interviews. Results showed that, after experiencing DSLM digital learning, students’ post‐CDT and delay‐CDT scores were significantly higher than pre‐CDT scores (p < 0.001, p < 0.01). Furthermore, Pearson correlation analysis indicated that students’ conceptual change (ΔCDT) was significantly correlated with motivational factors such as self‐efficacy (SE), active learning strategy (ALS), science learning value (SLV), achievement goal (AG), and learning environment stimulation (LES) (p < 0.05). Interviews also supported students’ motivational correlation to ΔCDT, particularly for SE, ALS, and AG.  相似文献

Background: Research has primarily concentrated on adults’ implicit theories about high quality science education for all students. Little work has considered the students’ perspective. This study investigated high school students’ implicit theories about what helped them learn science.

Purpose: This study addressed (1) What characterizes high school students’ implicit theories of what facilitates their learning of science?; (2) With respect to students’ self-classifications as African American or European American and female or male, do differences exist in the students’ implicit theories?

Sample, design and methods: Students in an urban high school located in south-eastern United States were surveyed in 2006 about their thoughts on what helps them learn science. To confirm or disconfirm any differences, data from two different samples were analyzed. Responses of 112 African American and 118 European American students and responses from 297 European American students comprised the data for sample one and two, respectively.

Results: Seven categories emerged from the deductive and inductive analyses of data: personal responsibility, learning arrangements, interest and knowledge, communication, student mastery, environmental responsiveness, and instructional strategies. Instructional strategies captured 82% and 80% of the data from sample one and two, respectively; consequently, this category was further subjected to Mann-Whitney statistical analysis at p < .05 to ascertain ethnic differences. Significant differences did not exist for ethnicity but differences between females and males in sample one and sample two emerged.

Conclusions: African American and European American students’ implicit theories about instructional strategies that facilitated their science learning did not significantly differ but female and male students’ implicit theories about instructional strategies that helped them learn science significantly differed. Because students attend and respond to what they think and perceive to be important, addressing students’ implicit theories may be one way to enhance science education reform.  相似文献

The present study examined the comparative effects of a prediction/discussion‐based learning cycle, conceptual change text (CCT), and traditional instructions on students' understanding of genetics concepts. A quasi‐experimental research design of the pre‐test–post‐test non‐equivalent control group was adopted. The three intact classes, taught by the same science teacher, were randomly assigned as prediction/discussion‐based learning cycle class (N = 30), CCT class (N = 25), and traditional class (N = 26). Participants completed the genetics concept test as pre‐test, post‐test, and delayed post‐test to examine the effects of instructional strategies on their genetics understanding and retention. While the dependent variable of this study was students' understanding of genetics, the independent variables were time (Time 1, Time 2, and Time 3) and mode of instruction. The mixed between‐within subjects analysis of variance revealed that students in both prediction/discussion‐based learning cycle and CCT groups understood the genetics concepts and retained their knowledge significantly better than students in the traditional instruction group.  相似文献

Abstract

In this study, the question was addressed which instructional conditions are required to teach students how they themselves can initiate and perform learning activities aimed at conceptual change. The CONTACT‐2 strategy (a computer‐assisted instructional strategy for promoting conceptual change in the domain of basic physical geography) served as starting point for the design of several training procedures aimed at enhancing self‐regulated learning. With the first experimental condition, strategic support was gradually withdrawn ('faded') within each instructional step, while, with the second experimental condition, the number of steps was reduced as the training continued. The original CONTACT‐2 condition served as control condition. Subjects were 65 fifth‐ and sixth‐graders (primary education). Dependent variables concerned students’ abilities to initiate and perform learning activities aimed at conceptual change, the quality of their conceptions, and their learning performance. Results suggested that ‘fading’ can be a fruitful instructional approach to foster self‐regulated learning aimed at conceptual change, provided that the ‘fading’ procedure is tuned to the students’ actual level of self‐regulated learning: external control should not be withdrawn until students are able (and prepared) to initiate and perform the learning activities being required. When these conditions are met, designing effective training procedures aimed at ‘learning for conceptual change’ seems possible.  相似文献

This study examines the impact of Disaggregate Instruction on students’ science learning. Disaggregate Instruction is the idea that science teaching and learning can be separated into conceptual and discursive components. Using randomly assigned experimental and control groups, 49 fifth‐grade students received web‐based science lessons on photosynthesis using our experimental approach. We supplemented quantitative statistical comparisons of students’ performance on pre‐ and post‐test questions (multiple choice and short answer) with a qualitative analysis of students’ post‐test interviews. The results revealed that students in the experimental group outscored their control group counterparts across all measures. In addition, students taught using the experimental method demonstrated an improved ability to write using scientific language as well as an improved ability to provide oral explanations using scientific language. This study has important implications for how science educators can prepare teachers to teach diverse student populations.  相似文献

The National Science Education Standards emphasise teaching unifying concepts and processes such as basic functions of living organisms, the living environment, and scale. Scale influences science processes and phenomena across the domains. One of the big ideas of scale is that of surface area to volume. This study explored whether or not there is a correlation between proportional reasoning ability and a student's ability to understand surface area to volume relationships. Students' knowledge of surface area to volume relationships was assessed pre and post to a one‐week instructional intervention involving investigations about surface area to volume as a limiting factor in biological and physical systems. Results showed that proportional reasoning scores of middle school students were correlated to pre‐test and post‐test assessment scores, and a paired‐sample t‐test found significant differences from pre‐test to post‐test for the surface area to volume assessment. Relationships between proportional reasoning, visualisation abilities and success in solving surface to volume problems are discussed. The implications of the results of this study for learning concepts such as magnitudes of things, limits to size, and properties of systems that change depending on volume and surface are explored.  相似文献

Background: Past studies have shown significant associations between students’ conceptions of learning science and their science learning self-efficacy. However, in most of the studies, students’ science learning self-efficacy has often been measured by a singular scale.

Purpose: Extending the findings of these studies, the present study adopted a multi-dimensional instrument to assess Taiwanese high school students’ science learning self-efficacy and investigate the relationships with their conceptions of learning science.

Sample: A total of 488 Taiwanese high school students (265 male and 223 female) were invited to participate in this survey.

Design and method: All the participants responded to the Conceptions of Learning Science (COLS) questionnaire regarding ‘Memorizing’, ‘Testing’, ‘Calculating and practicing’, ‘Increase of knowledge’, ‘Applying’ and ‘Understanding and seeing in a new way’ and the Science Learning Self-Efficacy (SLSE) instrument, including ‘Conceptual understanding’, ‘Higher-Order cognitive skills’, ‘Practical work’, ‘Everyday application’ and ‘Science communication’.

Results: The path analysis results derived from the structural equation modeling method indicated that, of all five SLSE dimensions, the ‘Understanding and seeing in a new way’ COLS displayed as a positive predictor, while the ‘Testing’ COLS was a significant negative predictor. The ‘Applying’ COLS item can only positively contribute to the SLSE dimensions of ‘Higher-Order thinking skills’, ‘Everyday application’ and ‘Science Communication’.

Conclusions: In general, students in strong agreement with learning science as understanding and seeing in a new way or the application of learned scientific knowledge are prone to possess higher confidence in learning science. However, students who consider learning science in terms of preparing for tests and examinations tend to hold lower science learning self-efficacy.  相似文献

Design‐based science (DBS) is a science pedagogy in which new scientific knowledge and problem‐solving skills are constructed in the context of designing artifacts. This paper examines whether the enactment of a DBS unit supported students’ efforts to construct and transfer new science knowledge and ‘designerly’ problem‐solving skills to the solution of a new real‐world design problem in a real‐world setting. One hundred and forty‐nine students participated in the enactment of a DBS unit. Their understanding of the curricular content was assessed by identical pre‐instructional and post‐instructional written tests. They were then given a new design problem as a transfer task. There was a statistically significant increase on scores from pre‐test to post‐test with an effect size of 1.8. There was a stronger correlation between the scores of the transfer task and those of the post‐test than with those of the pre‐test; we use this finding to suggest that the knowledge that was constructed during the unit enactment supported the solution of the transfer task. This has implications for the development of science curricula that aim to lead to the construction of knowledge and skills that may be useful in extra‐classroom settings. Whether participation in consecutive enactments of different DBS units increases transfer remains to be investigated in more depth.  相似文献

Health professionals and policymakers are asking educators to place more emphasis on food and nutrition education. Integrating these topics into science curricula using hand‐on, food‐based activities may strengthen students’ understanding of science concepts. The Food, Math, and Science Teaching Enhancement Resource (FoodMASTER) Initiative is a compilation of programs aimed at using food as a tool to teach mathematics and science. Previous studies have shown that students experiencing the FoodMASTER curriculum were very excited about the activities, became increasingly interested in the subject matter of food, and were able to conduct scientific observations. The purpose of this study was to: (1) assess 4th graders food‐related multidisciplinary science knowledge, and (2) compare gains in food‐related science knowledge after implementation of an integrated, food‐based curriculum. During the 2009–2010 school year, FoodMASTER researchers implemented a hands‐on, food‐based intermediate curriculum in eighteen 4th grade classrooms in Ohio (n = 9) and North Carolina (n = 9). Sixteen classrooms in Ohio (n = 8) and North Carolina (n = 8), following their standard science curricula, served as comparison classrooms. Students completed a researcher‐developed science knowledge exam, consisting of 13 multiple‐choice questions administered pre‐ and post‐test. Only subjects with pre‐ and post‐test scores were entered into the sample (Intervention n = 343; Control n = 237). No significant differences were observed between groups at pre‐test. At post‐test, the intervention group scored (9.95 ± 2.00) significantly higher (p = 0.000) than the control group (8.84 ± 2.37) on a 13‐point scale. These findings suggest the FoodMASTER intermediate curriculum is more effective than a standard science curriculum in increasing students’ multidisciplinary science knowledge related to food.  相似文献

A genuine interest in science is an important part of scientific literacy, and thus a critical goal for science education. Recent studies, however, have found that school science has not been effective in meeting this goal, an important reason for which is the lack of knowledge about what makes science interesting (or not) to the students. Using instructional episodes as the unit of analysis, this study investigated the effects of learning environment elements (content topic, activity, and learning goal) on student interest in science. The findings indicated that when judging the interestingness of an instructional episode, students focused primarily on the form of activity rather than content topic and learning goal. Activities that were “hands‐on” in nature and allowed for engagement with technology elicited higher interest. This study highlights the need to place more emphasis on the role of activity in constructing interesting learning environments, and in the mean time, suggests that student science interest could be improved by making changes to relatively easy‐to‐manipulate aspects of learning environments, such as those examined in the study. © 2012 Wiley Periodicals, Inc.

This study analyses middle school students’ interests in biology to provide information on instructional strategies and curriculum development in Korea. An instrument that measures interests was developed based on the middle school biology curriculum. It consists of 64 three‐point Likert‐type items (scores range from 0 to 2). The two components, ‘topic’ and ‘activity’, are composed of 64 items. The topic component and the activity component contain 11 domains and six domains respectively. Data were collected from 267 middle school students in Seoul (male: 169, female: 107). The levels of interest in topic and activity were almost the same and not high. The highest interest domains were ‘genetics’ in topics and ‘observing through a microscope’ in activities. The interest levels in the domain ‘plant morphology’ and ‘plant‐related activity’ were the lowest in each component. The interest level of the eighth graders was the highest found among students. Interest levels of females were lower than those of males in ‘environment and ecosystem’, ‘animal reproduction’ and ‘animal morphology’, but higher in ‘plant morphology’ and ‘plant related activity’ (p < 0.05). Among the topics, the ‘human biology’ domain correlated positively with the domains ‘genetics’, ‘environment and ecosystem’ and ‘respiration of animal and plant’. The correlation between the domains of ‘plant reproduction and nutrition’ and ‘plant development’ was significant in ‘activity’ (r > 0.50, p < 0.001). Consistencies in interests were suggested with respect to instructional strategy and curriculum design.  相似文献

To a science ‘outsider’, science language often appears unnecessarily technical and dense. However, scientific language is typically used with the goal of being concise and precise, which allows those who regularly participate in scientific discourse communities to learn from each other and build upon existing scientific knowledge. One essential component of science language is the academic vocabulary that characterises it. This mixed-methods study investigates middle school students’ (N?=?59) growth in academic vocabulary as it relates to their teacher’s instructional practices that supported academic language development. Students made significant gains in their production of general academic words, t(57)?=?2.32, p?=?.024 and of discipline-specific science words, t(57)?=?3.01, p?=?.004 in science writing. Results from the qualitative strand of this inquiry contextualised the students’ learning of academic vocabulary as it relates to their teacher’s instructional practices and intentions as well as the students’ perceptions of their learning environment. These qualitative findings reveal that both the students and their teacher articulated that the teacher’s intentional use of resources supported students’ academic vocabulary growth. Implications for research and instruction with science language are shared.  相似文献

ABSTRACT

Instructional explanations have sometimes been described as an ineffective way to teach science, representing a transmissive view of learning. However, science teachers frequently provide instructional explanations, and students also offer them in cooperative learning. Contrary to the transmissive view regarding explanation, studies suggest that instructional explanations might be successful if they are based on an interaction between explainers and explainees, including the diagnosis of understanding and adaptation to the explainee’s needs. The present article has three goals: (1) It will propose a framework for potentially effective instructional explanations, presenting five core ideas of what constitutes effective instructional explanations and two concerning how they should be implemented into science teaching. (2) To justify the framework, the article will review studies on the effectiveness of instructional explanations. It will identify factors that have been researched for their impact on the effectiveness of instructional explanations and discuss them for their applicability to science teaching. (3) This article will connect the research on instructional explanations with the idea of basic dimensions of instructional quality in science. It will discuss the core ideas as particular expressions of the basic dimensions of instructional quality, specifically ‘cognitive activation’ and ‘constructive support’.  相似文献

Generations of students are graduating from secondary school disinterested in post-secondary study of science or pursuing careers in science-related fields beyond formal education. We propose that destabilising such disinterest among future students requires science educators to begin listening to secondary school students regarding their views of how science learning is made interesting within the science classroom. Studies on students’ interest in response to instructional strategies applied in the classroom communicate the opinions (i.e. the ‘voice’) of students about the strategies they believe make their classroom learning interesting. To this end, this scoping study (1) collects empirical studies that present from various science and non-science academic domains students’ views about how to make classroom learning interesting; (2) identifies common instructional strategies across these domains that make learning interesting; and (3) forwards an instructional framework called TEDI ([T]ransdisciplinary Connections; Mediated [E]ngagement; Meaningful [D]iscovery; and Self-determined [I]nquiry), which may provide secondary school science teachers with a practical instructional approach for making learning science genuinely interesting among their students within the secondary school science classroom context.  相似文献

During their years of schooling, students develop perceptions about learning and teaching, including the ways in which teachers impact on their learning experiences. This paper presents student perceptions of teacher pedagogy as interpreted from a study focusing on students' experience of Year 7 science. A single science class of 11 to 12 year old students and their teacher were monitored for the whole school year, employing participant observation, and interviews with focus groups of students, their teacher and other key members of the school. Analysis focused on how students perceived the role of the teacher's pedagogy in constructing a learning environment that they considered conducive to engagement with science learning. Two areas of the teacher's pedagogy are explored from the student perspective of how these affect their learning: instructional pedagogy and relational pedagogy. Instructional pedagogy captures the way the instructional dialogue developed by the teacher drew the students into the learning process and enabled them to “understand” science. How the teacher developed a relationship with the students is captured as relational pedagogy, where students said that they learned better when teachers were passionate in their approach to teaching, provided a supportive learning environment and made them feel comfortable. The ways in which the findings support the direction for the middle years and science education are considered.  相似文献

We present the results of a literature review of studies on teaching strategies for moral education in secondary schools (1995–2003). The majority of the studies focus on the ‘what’ and ‘why’, i.e. the objectives, of curriculum‐oriented moral education. Attention to the instructional formats for enhancing the prosocial and moral development of students (the ‘how’) is relatively sparse. Most studies on teaching strategies for moral education recommend a problem‐based approach to instruction whereby students work in small groups. This approach gives room for dialogue and interaction between students, which is considered to be crucial for their moral and prosocial development. Other studies discuss more specific teaching methods, such as drama and service learning. We conclude that the theoretical discourses on moral education are not reflected on the practice of curriculum‐oriented moral education and its effects on students’ learning outcomes. We recommend that future research on curriculum‐oriented moral education includes the subject areas encompassing moral issues and the social differences between students.  相似文献

The outcomes of a pilot Service‐learning Program designed for pre‐service teachers enrolled in a unit about inclusive education in an Australian University will be discussed in this paper. Service‐learning requires university or school students to become involved in their community in order to utilize knowledge learned at university. The program involves reciprocal relationships with organizations in which the service reinforces and strengthens the learning in the academic unit on inclusive education, and the learning reinforces the service for the organization. Pre‐service teachers completed 10 hours working in the community along with completing a service‐learning reflection log. Evaluation of the service‐learning reflection process as a pedagogy will be discussed using the conceptual lenses: technical, cultural, political and post modern. The data demonstrate evidence to suggest that Butin's four lenses can be supported by the reflection process associated with the Service‐learning Program described in this study and be used to construct an improved service‐learning reflection log for future students.  相似文献

The background of the study is the theory of basis models of teaching and learning, a comprehensive set of models of learning processes which includes, for example, learning through experience and problem‐solving. The combined use of different models of learning processes has not been fully investigated and it is frequently not clear under what circumstances a particular model should be used by teachers. In contrast, the theory under investigation here gives guidelines for choosing a particular model and provides instructional sequences for each model. The aim is to investigate the implementation of the theory applied to physics instruction and to show if possible effects for the students may be attributed to the use of the theory. Therefore, a theory‐oriented education programme for 18 physics teachers was developed and implemented in the 2005/06 school year. The main features of the intervention consisted of coaching physics lessons and video analysis according to the theory. The study follows a pre‐treatment‐post design with non‐equivalent control group. Findings of repeated‐measures ANOVAs show large effects for teachers' subjective beliefs, large effects for classroom actions, and small to medium effects for student outcomes such as perceived instructional quality and student emotions. The teachers/classes that applied the theory especially well according to video analysis showed the larger effects. The results showed that differentiating between different models of learning processes improves physics instruction. Effects can be followed through to student outcomes. The education programme effect was clearer for classroom actions and students' outcomes than for teachers' beliefs.  相似文献

Abstract

This is a multiple‐indicators evaluation of an innovative approach, using self‐paced learning modules accompanying computerised exercises as an adjunct to teaching quantitative concepts and skills to environmental science students at university. The evaluation data, based on a pre‐unit and a post‐unit questionnaire survey completed by 38 students, show high levels of student satisfaction with the unit as a whole, and the self‐paced workbooks in particular. Students also indicated a clear preference for learning from self‐paced workbooks compared to learning from textbooks. Some students applied the quantitative skills acquired to other academic units, or took the initiative to learn to use additional statistical procedures (not covered in the unit) for academic purposes. However, comparison of students’ levels of interest and confidence in quantitative subjects before and after the completion of the unit did not yield significant changes. Implications of the research findings for university science education are discussed.  相似文献
